Abstract: The purpose of this research is to investigate the physical mechanisms associated with broadband tip vortex noise caused by rotating wind turbines. The flow and acoustic field around a wind ...

Abstract: A three-dimensional Navier-Stokes code with pseudo-compressibility, an implicit formulation of finite difference, and a k – ε two-equation turbulence model has been developed for the Francis ...

Abstract: A 1-kW small horizontal-axis wind turbine “Airdolphin,” capable of high wind operation up to 50 m/s without pitch control system, is now under global round robin tests. The present paper reports ...
